Diamond Shape Topology on a Flat Surface With No Deformation Planned
Your loop flow being good or bad is mostly depend on what you want to do with it.
on a flat surface that does not deform, and it has support loop on top and bottom so it's good to me at least.
on a high deformed surface it &quot;might&quot; cause problems.
as I see now your model is a hard surface and you did it on a flat surface and I don't thing it will ever deform so you are ok.
some might use their loop flow to make new parts out of it or help make stuff separate or help make textures.
